Product details
Overview
ADM13307-4ARZRL7 from Analog Devices is a triple voltage supervisor IC designed to monitor three independent supply rails in microprocessor and DSP systems. It features one fixed 2.25 V threshold (SENSE1) and two adjustable 0.6 V thresholds (SENSE2, SENSE3), operates from 2.0 V to 5.5 V, draws ≤40 μA supply current, and provides 140 ms minimum reset timeout. It is used in notebook computers for reliable power-on reset sequencing.
For engineers reviewing the ADM13307-4ARZRL7 datasheet, ADM13307-4ARZRL7 pinout, ADM13307-4ARZRL7 application, or ADM13307-4ARZRL7 equivalent, key selection criteria include its dual-adjustable 0.6 V sense inputs, push-pull active-high/active-low RESET outputs, manual reset (MR) support, −40°C to +85°C operation, and 8-lead SOIC_N package compatibility with space-constrained embedded designs.
Technical Context
The ADM13307-4ARZRL7 implements undervoltage monitoring using internal comparators with hysteresis (0 mV at 0.6 V inputs, 20–30 mV at 2.25 V input) and a precision oscillator-based 140–280 ms reset timeout timer. Its SENSE2 and SENSE3 inputs accept externally configured thresholds via resistor dividers referenced to the 0.6 V internal reference.
It supports simultaneous assertion of both RESET (active low) and RESET (active high) outputs during fault conditions, with guaranteed valid reset behavior down to VDD = 1.1 V. The MR input accepts logic-level or push-button signals and triggers a full reset timeout cycle upon rising-edge release.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports wide-input industrial and portable systems without external regulation. |
| Fixed Threshold (SENSE1) | 2.25 V (typ) - monitors 2.5 V rail with ±2% tolerance over temperature, enabling precise brownout detection. |
| Adjustable Thresholds (SENSE2/3) | 0.6 V (typ) - allows resistor-divider configuration to monitor any higher voltage rail (e.g., 1.2 V, 1.8 V, 3.3 V). |
| Reset Timeout | 140 ms (min) - ensures stable power-up before processor release, meeting typical microcontroller reset timing requirements. |
| Supply Current | ≤40 μA - enables always-on supervision in battery-powered applications without significant drain. |
| Operating Temperature | −40°C to +85°C - qualified for extended industrial environments including automotive infotainment and industrial computing. |
| Output Type | Push-pull RESET and RESET - eliminates need for external pull-up resistors and supports direct interface to CMOS/TTL inputs. |
Pinout & Package
ADM13307-4ARZRL7 is housed in an 8-lead narrow-body SOIC (SOIC_N, R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SENSE1 | Fixed-threshold voltage monitor input | Monitors 2.5 V supply directly; threshold = 2.25 V (typ), with 20 mV hysteresis. |
| 2 - SENSE2 | Adjustable-threshold voltage monitor input | Configured via external resistor divider to monitor any rail ≥0.6 V; reference = 0.6 V (typ). |
| 3 - SENSE3 | Adjustable-threshold voltage monitor input | Independent second adjustable input; same 0.6 V reference and hysteresis as SENSE2. |
| 4 - GND | Analog and digital ground reference | Single ground connection; requires low-impedance PCB return path for noise immunity. |
| 5 - RESET | Active-low push-pull reset output | Drives low during fault or power-up; sinks up to 2 mA at 3.3 V with VOL ≤ 0.4 V. |
| 6 - RESET | Active-high push-pull reset output | Drives high during fault or power-up; sources up to 2 mA at 3.3 V with VOH ≥ VDD − 0.4 V. |
| 7 - MR | Manual reset input | Active-low; initiates full reset timeout when pulled low; supports push-button or FPGA-controlled reset. |
| 8 - VDD | Power supply input | Accepts 2.0–5.5 V; internal circuitry remains functional down to 1.1 V for early reset assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Dual adjustable 0.6 V sense inputs | Enables monitoring of two additional rails (e.g., core and I/O voltages) using simple resistor dividers-no external references required. |
| Guaranteed reset assertion at VDD ≥ 1.1 V | Ensures reliable power-on reset initiation even during slow or noisy power ramp-up, critical for flash memory initialization. |
| Push-pull RESET/RESET outputs | Eliminates external pull resistors, reduces BOM count, and improves noise immunity versus open-drain alternatives. |
| 140–280 ms programmable reset timeout | Provides sufficient delay for PLL lock, memory initialization, and clock stabilization before processor release. |
| −40°C to +85°C industrial temperature range | Validated for deployment in uncontrolled thermal environments such as factory automation controllers and portable medical devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6816TPA+T | Triple supervisor with fixed 2.93 V / 2.63 V / 2.32 V thresholds; no adjustable inputs; 200 ms reset timeout. | Best suited for fixed-rail systems (e.g., legacy 3.3 V/2.5 V/1.8 V only); lacks flexibility for custom voltage monitoring. | Select when design uses only standard supply voltages and requires lower quiescent current (25 μA). |
| TPS3808G33DBVR | Single-channel supervisor with 3.3 V fixed threshold; requires three units plus logic to replicate triple function; 200 ms timeout. | Increases component count, layout area, and routing complexity; no native dual-output or MR support. | Choose only if existing design already uses TPS3808 family and board space permits replication. |
Compared with MAX6816TPA+T and TPS3808G33DBVR, the ADM13307-4ARZRL7 uniquely integrates two user-configurable 0.6 V sense inputs alongside one fixed 2.25 V input in a single SOIC-8 package, enabling compact, flexible rail monitoring without external references or multiple ICs.

FAQ
What is the exact threshold voltage for SENSE1 on the ADM13307-4ARZRL7?
The ADM13307-4ARZRL7 has a fixed SENSE1 threshold of 2.25 V (typical), with min/max values of 2.20 V and 2.32 V across −40°C to +85°C. This setting is factory-trimmed and does not require external components. The value is specified in Table 2 of the ADM13307 Rev. 0 datasheet and applies exclusively to the ADM13307-4ARZRL7 variant.
Can SENSE2 and SENSE3 on the ADM13307-4ARZRL7 monitor different voltages?
Yes - SENSE2 and SENSE3 each use the internal 0.6 V reference and can be independently configured via separate resistor dividers to monitor distinct supply rails (e.g., 1.2 V core and 3.3 V I/O). The ADM13307-4ARZRL7 datasheet confirms this dual-adjustable capability in the Ordering Guide and Theory of Operation sections.
Does the ADM13307-4ARZRL7 support manual reset deassertion with a timed release?
Yes - when the MR pin transitions from low to high, the ADM13307-4ARZRL7 holds RESET and RESET asserted for the full reset timeout period (140–280 ms) before releasing. This behavior is documented in Figure 15 and the Manual Reset section of the ADM13307-4ARZRL7 datasheet.
What is the maximum sink/source current capability of the RESET and RESET outputs on the ADM13307-4ARZRL7?
The ADM13307-4ARZRL7 RESET (active low) output sinks up to 2 mA at 3.3 V (VOL ≤ 0.4 V) and 3 mA at 5.5 V. The RESET (active high) output sources up to 2 mA at 3.3 V (VOH ≥ VDD − 0.4 V) and 3 mA at 5.5 V. These values are specified in Table 2 under "RESET, RESET Output".
Is the ADM13307-4ARZRL7 RoHS compliant and lead-free?
Yes - the "Z" suffix in ADM13307-4ARZRL7 denotes RoHS compliance per Analog Devices' ordering guide. The device uses lead-free matte tin finish on leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), suitable for standard reflow processes without special handling.
